BOOK MARKER Application led April 20,

My invention relates to book markers or indicators to be permanentlyattached to books so that the reader may simply and quickly indicate thepage at which the next reading of the book is to be commenced and it ismy object to produce a device which will be thin, light and cheap andwhich will not increase the thickness of the book to which it isattached and which can be easily attached to a book.

In the drawing I have shown one embodiment of my invention but it isobvious that the size, shape and materials may be varied withoutdeparting from my invention.

Fig. l is aplan view, partly broken away, of the book marker on theinside cover of a book; Fig. 2 a sectional view of the structure of Fig.l on the line 2 2 thereof and Fig. 3 a horizontal, sectional view of thestructure of Fig. l.

The device consists of two sheets of thin material, such as paper,Bristol board, celluloid, stiffened cloth, or the like with slidersbetween them. The base sheet 1 is provided with an adhesive on its backso that it may be readily secured to the inside of a book. The facesheet 2 has a plurality of openings 3, i and 5 therein. three of theseopenings being sufficient to care for a book of 999 pages.

The movable strips 6, 7 and 8 lie between the base sheet l and the facesheet 2 and each is behind an opening in the front sheet. The Y base andfront sheets are secured together by pasting as indicated by thestippling in Fig. l between the strips so that channels are formed inwhich the strips 6, 7 and 8 may slide. Each strip bea-rs numerals from lto 0, which numbers are successively visible through the openings in thefront sheet over the appropriate strips.

In use the adhesive on the back of the base sheet is moistened and thedevice attached, preferably to the inside cover, to a book becoming a.permanent part thereof. If the reader stops reading at any particularpage the movable strips are pulled from either end and slid in thechannels until the desired page number appears in the 'openings Oncontinuing the reading at any future time it is only necessary to lookat the marker or inoR INDICATOR 1928.

dicator and turn to the page. As the indicator is a permanent part ofthe book it cannot become lost or misplaced. y

The device is so simple and cheap that each book in a library may beprovided with one and the face sheet may also be a book` plate for theowner of the book.

I claim A book marker or indicator comprising a base sheet coated withadhesive on its back face whereby it may be secured to a book and a facesheetprovided with openings therein, the two being secured together atintervals whereby channels are formed between them under the openings,and strips, one of which is slidable in each channel and each providedwith numerals successively visible through the openings, the strip endsprojecting beyond the base and face sheets.

In testimony whereof I have hereunto subscribed my name.
